Hi , I made a new account and I went 124-14 on nuketown and got a nuclear and it shows all this in theater mode , but it doesn't register the medals or stats . Thanks in advance for any responses . The game played is saved on my Ambien_Dream account .

What platform are you playing on? You don't need to post your GT ... in fact, it is advised that you do not do so. If you are playing on a console, if either you or the host dashboarded from the game, the stats will never show up. In any case, more information is needed in order to figure out what happened.

Just a thought, there might be some delays on the data transfer. It may also be caused when connecting your console through a wireless internet connection. It is more advisable if you will connect your console through a wired connection and just wait for it to update. It should show up.
